Nice, but I notice two useful additions and one error. Additions: 'wan' and 'kulupu' (and 'kulupu kulupu' and probably so on) for places. That may be too many and too complicated, but a name every three-five columns is a good idea (see all the world systems, though the E does do every column). Error: not 'wan kulupu' etc. but 'kulupu wan' etc. I like the fingers, but that is usefully extended to decimals and beyond. Still. this is a natural for tp or tresimals.

Yes, I think you are right. That's why I hesitated (quibbled with myself) over stating that I wasn't naming them. Did I accidentally name them by attempting to refer to them in the only way I know how to do? That would be an "organic" addition.

If it were not in the context of me laying out candies, I think I would have said kulupu nanpa, kulupu kulupu nanpa.

just 'kulupu nanpa', 'pi' requires two following words. Now, it is not clear whether the next step is 'kulupu kulupu nanpa' or 'kulupu pi kulupu nanpa', that is, whether we group groups and then note that the members of the bottom level group are numbers or start with groups of numbers and then group them (I keep thinking that one or the other of several set theories ought to make this clear, though at least L-sets won't distinguish them and that may be he best solution of all). In any case, 'nanpa' is probably redundant in this context. And 'kulupu' gets overwhelming fairly early on, suggesting some sort of power notation like all the standard ones (based on thousands or 10,100s or whatever) and, of course, using these (whatever they may be) for vague general numbers, skipping the details below the top levels, "$2M" for example, for what some bean counter probably has down to the penny.

I haven't worked this through yet, but I wonder about some way of saying for large numbers in the range of millions, "kulupu nanpa mute tu wan wan" (meaning, "a base 3 reversed positional number with 14 place columns") like we might say "a 7 digit salary" in English.
